This book was released on 2023-06-15 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology is an interdisciplinary field comprising materials scientists, chemists, physicists, and engineers dedicated to understanding the chemistry behind the associated synthesis, purification, modification, and applications. Already, nanotechnology has been instrumental to advances in medicine, electronics, catalysis, and cosmetics. The work of nanotechnologists has enabled society to move from the current “Silicon Age” into a new “Nano Age.” These alternatives to Si-based technologies are expected to combine the optoelectronic properties of bulk inorganic semiconductors with the benefits of additive device manufacturing—low cost, large area, and solution-based processes. This primer focuses on a class of nanomaterials known as colloidal quantum dots. Known for their solution processability and size-dependent optoelectronic properties, the study of colloidal quantum dots has garnered significant attention from the research community. The goal of this primer is to equip newcomers with the introductory knowledge and tools necessary to enter the field. As such, the scope of our work focuses on the synthesis and characterization of quantum dots; where possible, we point the reader to further reading specific to applications.

Available in PDF, EPUB and Kindle. Book excerpt: "Zinc oxide Nanoparticles, also known as quantum dots, have been synthesized with sizes ranging from 1 to 19 nm. Quantum dots are a developing form of semiconductor that have several possible advantages over traditional silicon based semiconductors. For example, instead of needing to undergo tedious and expensive doping procedures to generate wide and tunable band gap ranges as in the case of traditional silicon-based semiconductors, quantum dots can create wide and tunable band gap ranges based simply on their size. Furthermore, as a result of their band gaps quantum dots are capable of fluorescing different colors when excited by a UV light source. The one nanometer dots observed in my experiments, for instance, have a violet fluorescence with an ideal peak at 421 nm; whereas the violet semiconductor indium gallium nitride currently used in systems need up to 1000nm to peak. These zinc oxide dots were studied starting with the synthesis methods to determine the best way to produce a full range of fluorescence colors; then their size UV absorbance and fluorescence spectrums were taken and examined; and finally the sizes of the dots were measured with three different methods. The agreement of the results from the three methods used in my experiments provides greater understanding of the basic aspects of the dots and aid the development of a simple, but effective equation to relate the dot size to band gap size."--

Download or read book Synthesis and Characterization of Doped Core shell Quantum Dots written by Elizabeth J. Sodt and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The central theme of the research performed is the systematic modification of the optical properties of quantum dots by the formation of a shell of another quantum dot of a different band gap energy. Core/shell quantum dots such as CdS:Mn/CdS. CdS:Mn/ZnS, and ZnS:Mn/CdS with various concentrations of dopant Mn2 in the core and shell concentrations have been synthesized under mild conditions in the aqueous phase using stoichiometric amounts of the surfactant stabilizer dodecyl sulfate. These quantum dots exhibit UV-vis, emission, and electron paramagnetic resonance (EPR) spectral behavior that is dependent on the concentration of the shell and the dopant Mn2 in the core. The emission intensities of the core quantum dots do exhibit a systematic variation with Mn2 concentration. When a shell is added a systematic variation in the emission intensity and lifetime that are inversely proportional to the concentration of the shell is observed. When the large band gap ZnS is added as a shell to the small band gap CdS, the Mn2+ ions migrate from the core to the shell which is manifested in the emission and EPR spectra. Additionally the mixing of the valence and conduction band energy states of the large and small band gap shell and core respectively is also manifested in the emission spectra. In the reverse case, namely when CdS is added as a shell to ZnS the migration is not observed and the mixing of the valence and conduction band energy levels is minimum. The tunable optical properties of these core/shell quantum dots make them excellent platforms for the generation of nanosensors for nerve gas analogs.
